I have a Trans that was built about 8-9 years ago sitting in the garage it has about 1 years worth of use behind a very week motor then it sat. The Trans never felt perfect but I also never had a good converter (not even a Stock D5)

So now my current trans (stock 2004R out of a 4.3 Monte) is dieing and I am going to put the "Built" Trans on the car and would like to now what "things" I could do to it to make it work like a solid BRF trans.

The car is almost all stock
I am going to use a used stock D5 (from a board vendor)

The Trans has or should have all art carr stuff from the late 90's
1-billet servo
2-clutches
3-band
4-up graded front pump.
Id say about $1100.00 of art car stuff.
Including a stator support that broke with in a week.
I also put a B&M shift kit on it. Before it was sent to the shop.

Before I put the Trans in the car WHAT WOULD YOU DO TO IT?
Of course on a SMALL budget.
Thanks guys for your help.
